Troubleshooting
Cleaner Not Moving

Poor Cleaning Performance
- Clean the filter basket. A clogged filter reduces suction.
- Ensure the pool water chemistry is balanced.
- Check for any blockages in the suction inlets.
Signal Delay (Cell Phone Function)
The cell phone function can monitor cleaning, but the signal may be delayed when the product is underwater. This is normal operation and not a malfunction.
